Notre Dame is only 3-1. This season could still go multiple directions. But if — IF — it continues to trend upward, one moment from this weekend may stand the test of time as the demarcation point between a successful 2017 and a new Irish head coach in 2018. When junior cornerback Shaun Crawford peanut-punched the ball away from Spartans junior running back LJ Scott at the goal line in Saturday night’s second quarter, Crawford certainly altered the game.

That is the very smallest effect of that heads-up play.

It may have altered the trajectory of the entire program. Until coming weeks play out, that claim needs to remain in the conditional verb tense. If the time comes where removing that particular phrasing is appropriate, the statement will not be one of exaggeration. It was that big of a play.

If granting that premise, and acknowledging the usage of “program” implies its reach could extend past this season, a look at Notre Dame’s travel roster from this weekend raises an eyebrow.

The listing included 72 names, complete with a number of walk-ons. If looking at the scholarship players, the strictest of readings finds only 11 names whom the Irish should not plan on having around in 2018.

The obvious, players currently in their last year of eligibility: linebackers Greer Martini and Nyles Morgan, defensive end Andrew Trumbetti, tight end Durham Smythe, left tackle Mike McGlinchey, offensive lineman Hunter Bivin and receiver Cam Smith.

The almost-assuredly headed to the NFL: left guard Quenton Nelson.

The very-unlikely to be asked back for a fifth year: offensive lineman Jimmy Byrne, receiver Austin Webster and quarterback Montgomery VanGorder.

Of those 11, only seven contributed to the 38-18 victory over Michigan State.

Obviously there will be other departures, either due to transfer or early entry into the NFL Draft or perhaps injury, but the point is: Much of this team will be back in a year. Even more pertinently, the rout of the Spartans was done with youth, as contrary to the norm as that may be. It seems safe to assume that youth has yet to reach the ceiling on its potential.

Among those contributors, it is time to start a Justin Yoon record watch. It is preemptive, but the junior kicker has reached a point where any week he could essentially set the Notre Dame career field goal percentage record, though he remains a bit further from the mark being recognized.

Entering the season, Yoon had made 28-of-34 field goal attempts. Thus far this year, he has added 5-of-7 to the ledger, making for an 80.49 percent career rate. John Carney (1984-1986) holds the Irish record at 73.9 percent. If Yoon makes four of his next nine attempts, he will break that mark. Technically speaking, he will not set the record until he has indeed taken nine more attempts, notching the minimum requirement of 50.

Notre Dame has turned 19 trips into the red zone into 17 touchdowns to date. By no means has the Irish offense needed to rely on Yoon. By no means is this mention a subtle expectation of that changing. It is simply comprehensibly feasible to think Yoon might make four field goals in one weekend. After all, he has twice made three in one game.

One of those occasions came against Stanford in 2015. Taking a look at this year’s Cardinal, it held on for a win against UCLA late Saturday night. The 58-34 shootout sparked two thoughts. First of all, junior running back Bryce Love is really good. Let’s skip finding creative adjective and memorable phrasing and instead get straight to that point. He is really, really good.

In four games this year, Love has taken 73 carries for 787 yards, averaging 196.75 yards per game and 10.8 yards per rush.

Those numbers are absurd.

Secondly, Stanford is already almost certain to fall short of preseason projections. The over/under win total number for the Cardinal was nine. At 2-2 currently, the over is still within reach if Stanford wins out, but that would require beating winning all of, in chronological order, vs. Oregon, at Washington State, vs. Washington and vs. Notre Dame.

On the other side of that spectrum, Wake Forest is poised to surpass expectations. The Demon Deacons are 4-0 after blocking a potentially game-winning field goal by Appalachian State on Saturday. Wake Forest has gotten off to the strong start in large part thanks to its defense, allowing only 11.5 points per game.

Notre Dame fans can take that to mean Irish first-year defensive coordinator Mike Elko, formerly in that same role with the Demon Deacons, did not have much of a determining effect on that defense’s success, or they can see that stifling unit’s continued growth as a sign of Elko’s developmental contributions to the individual players.

Anyway, the over/under win total of Wake Forest was 5.5. The Deacons could still fall short of that, but they would need to manage only one win from trips to Georgia Tech and Syracuse as well as a visit from Duke, while also not pulling off any surprises.

When Notre Dame got five heralded defensive line recruits on campus together in January, it turned heads. When Irish defensive line coach Mike Elston offered public optimism about the possible 2019 commitments, it raised expectations.

“Honestly, just talking with the guys today — Jacob Lacey, Mazi Smith, Joseph Anderson, Nana Osafo-Mensah, and myself — if Notre Came can land all of us, that would be the dream d-line class for Notre Dame,” Spears told Irish Illustrated. “I could see another pass-rusher or two, also.”

The other three names Spears mentioned all joined Lacey and him on Jan. 27 at an on-campus Junior Day. All five qualify as consensus four-stars, with Smith (East Kentwood; Kentwood, Mich.) a tackle, Anderson (Siegel; Murfreesboro, Tenn.) an end, and Osafo-Mensah (Nolan Catholic; Fort Worth, Texas) a possible end/linebacker hybrid.

Landing all five may be ambitious, but it would also be the envy of most of the country.

Spears already held offers from the likes of Alabama and Michigan State, despite missing his junior season with a knee injury. The Irish extended a scholarship offer to him in June, prompting an unofficial visit to watch a 49-14 Notre Dame victory over USC in October. In a video released by 247Sports.com, Spears cited that experience as one of the three primary reasons he committed, along with the educational opportunity and the “overall tradition and culture.”

Spears shows quickness for a defensive lineman, but not such that he would ever be considered an outside linebacker in any form. His size makes him an ideal candidate to set the edge against the run or possibly move inside when the Irish need a quicker defensive line to handle certain opponents. His agility, though, will make him a three-down threat, both a pass-rusher and an edge-setter.

Notre Dame currently has depth at defensive end, but with only one signed in the class of 2018 (Justin Ademilola) and one remaining from the class of 2017 (Kofi Wardlow), an influx will be a priority this recruiting cycle. Spears will theoretically have one season to adjust to collegiate competition before the quartet of rising juniors Daelin Hayes, Khalid Kareem, Julian Okwara and Ade Ogundeji run out of eligibility. (The first three have two seasons remaining, while Ogundeji has the possibility of three more years.)

Hence, that Junior Day emphasis and Elston’s confidence on National Signing Day.

“I’ve been at Notre Dame now going on for nine years, and I haven’t had a stronger group of underclassmen that I’m recruiting than I have this year in 2019,” Elston said. “This could be the best defensive line haul we’ve ever had here.”

Expect to read that quote again and again (and possibly again) if any of the remaining three in the above photo follow Spears’ and Lacey’s lead.

Notre Dame will open spring practice in about two weeks. As always, the proceedings will be filled with positive reviews, optimistic outlooks, and an injury or two.

A quick look at each position group should lend a better understanding to those perspectives and effects, beginning with the group lacking many questions — the running backs. The biggest reason there is relative certainty around the running backs is there are just so few of them following the winter dismissals of rising junior Deon McIntosh and rising sophomore C.J. Holmes.

Depth Chart Possibilities:At some point, either Williams or Jones will be named the Irish starter. It is quite possible that will be a distinction without much difference, as the two could certainly complement each other well in offensive coordinator Chip Long’s system, which already prefers to use multiple running backs.

Human nature, though, dictates is more likely one back receives a majority of the carries.

Biggest Question:If Williams lines up with the No. 1 offensive unit in the Blue-Gold Game (April 21) to conclude spring practice, that will be the first genuine and tangible evidence he has improved as a pass blocker. Despite his big-play speed and seeming-ease breaking tackles, Williams’ one-dimensional game rendered him as much a liability as an asset in 2017.

Even in the Citrus Bowl victory, Williams followed up back-to-back rushes for a combined 36 yards with a blown pass protection resulting in a 13-yard sack.

“You have to be able to protect the quarterback with all positions,” Long said Feb. 7. “That dictates a whole lot if you’re going to play a lot or just be a situational guy. It’s something you have to embrace, the physicality.

“… That’s really the main thing, other than protecting the ball, that’ll keep a back off the field in our offense.”

The best ability is availability, and both an ankle injury and a balky quad limited Williams in that respect in 2017. Little blame can be cast for the natural bruises of football. Nonetheless, he will need to “embrace the physicality” if he wants to become more than a situational back.

Otherwise, Jones will be the default option. He has already shown a knack for both pass blocking and catching, making him a three-down option. Notre Dame will always prefer that rather than tip its hand to a running play every time Williams enters the game.

2017 Statistically Speaking:Obviously, Josh Adams carried the burden in the running game last season. Behind rising senior quarterback Brandon Wimbush and McIntosh, Williams was only the No. 4 rusher on the roster in yards and touchdowns, while Jones was No. 4 in carries and No. 5 in yards and scores.

“Since I’ve been here, if you look at the average rankings, we’re anywhere from 5 to 15,” Kelly said on 2017’s National Signing Day, a day on which Notre Dame secured the No. 13 class in the country, per rivals.com. “We’re going to fall somewhere in that range because there’s a line there we can’t get over based upon what our distinctions are here. That line is going to keep us between 5 and 15.

“We know where we’re going to fall. We’re going to continue to recruit the right kind of kids here.”

Sure enough, the Irish once again fall into that spectrum in 2018, finishing No. 11 per rivals. Though Notre Dame has risen above that range once (No. 3 in 2013) and fallen below it once (No. 20 in 2012) during Kelly’s tenure, his overall analysis remains accurate.

The instinct has always been to cite University academic standards as the greatest hurdle to rising into the top five consistently, but another aspect should not be overlooked. In a recent mailbag, Sports Illustrated’s Andy Staples pondered the factors keeping the Irish from becoming a perennial 10-win team.

“Another major reason is a lack of a local recruiting base,” Staples wrote. “No program has a stronger national reach than Notre Dame, but that still doesn’t make recruiting nationally easy. It’s much easier to have hundreds of quality prospects within driving distances.”

Looking at both this past year’s recruiting rankings and the last nine years of rankings underscores and supports Staples’ point.

Rivals considered 33 prospects to be five-star recruits in 2018. Only seven schools managed to sign multiple such players: Georgia (8), Clemson (6), USC (5), Alabama (3), Ohio State (3), Penn State (2), and Miami (2). To speak more broadly, four schools in the Deep South, two in the Ohio-Pennsylvania corridor and one in California, all talent-rich areas, especially compared to Indiana, Illinois and Michigan.

If combining the total signees of both four- and five-star rankings by rivals, Notre Dame signed 12 such prospects. Only 11 schools signed more, including six of the above seven. (Clemson equaled the Irish haul, though its even split between four- and five-star recruits stands out compared to Notre Dame’s 12 four-stars.) The additional five: Oklahoma, Texas, Florida State, Auburn and Florida. In other words, two schools tapping into Texas, two schools within Florida and one more in the Deep South.

If looking at the last nine years of recruiting, the span of Kelly’s time in South Bend, only eight programs have consistently out-recruited the Irish, all but one mentioned already. LSU finished with the No. 13 recruiting class in 2018, lowering its nine-year average placement to 8.0. The Tigers are one of five SEC teams in that group of eight, joining Florida State, Ohio State and USC.

Sense a theme?

It will always be hard enough for Notre Dame to find high-caliber players likely to succeed at a strong academic institution in the Midwest. That task is even harder knowing how far away those players typically are to start with.

Other programs face a similar challenge, and few handle it as well. Consider the 2018 recruiting classes of Stanford, Michigan and Michigan State, for familiar context.

Stanford finished with 4 four-stars in rivals’ No. 63 class. The Wolverines pulled in 7 four-stars as part of the No. 24 class, while the Spartans signed 5 four-stars in the No. 26 grouping.

The Blue-Chip RatioFinishing within Kelly’s range has not stopped Notre Dame from consistently having one of the most-talented rosters in the country. If abiding by rivals rankings for consistency, 45 of the 89 players currently on the Irish roster (including incoming freshmen) were four- or five-star recruits.

A commonly-cited metric of a roster’s talent is the so-called “Blue-Chip Ratio.” Essentially, a national championship caliber team will have at least 50 percent of its roster consisting of former four- or five-star prospects. Entering 2017, Notre Dame was one of only 10 such teams in the country.

As should be expected, the other nine included six programs from the Deep South, Ohio State, USC and, as an ode to Jim Harbaugh’s early recruiting successes, Michigan.

A Presidents Day ReminderNotre Dame cannot officially claim any POTUS as an alum, but both Josiah Bartlet and James Marshall would like to argue otherwise.

Notre Dame used the first early signing period to its advantage, but in many respects, succeeding in that initial foray was by default. The Irish already had strong relationships with the recruiting class of 2018 when the NCAA finally agreed upon setting a 72-hour window for December. No other recruiting changes went into effect in the cycle, so the only shift was getting the paperwork ready and the grades verified six weeks earlier than usual.

“When you are presented with a new rule that gives you — go ahead, sign them early — and you’ve done all that work, that’s kind of a lay-up,” Notre Dame head coach Brian Kelly said on National Signing Day, Feb. 7. “The real work now begins with the early visits.”

A bit before finally nailing down the December early signing period, the NCAA also approved official visits for high school juniors in April, May and June. Previously, a recruit could not take an official visit until September of his senior year in high school.

For a program with a national reach in recruiting — pulling in multiple prospects from both coasts in the cycle of 2018, for example — it can be difficult to get a player to visit for a home game amidst his own football season. When it is possible, it is often a rushed trip. The recruit plays a high school game Friday night, flies to South Bend, possibly via Chicago, early Saturday morning and then departs mid-day Sunday to get back home in time for the school week.

Notre Dame can now instead slate that official visit for the summer, perhaps around a camp environment or the Blue-Gold Game (April 21).

In years to come, this expedited timing could have a greater effect on recruiting than the early signing period does.

“How we handle the back end of it, the back end being when are those visits going to start, when do you start them, when do you end them,” Kelly said, “That’s really what we’re trying to figure out at this point relative to tweaking and how that’s going to work.”

Theoretically, earlier visits could lead to earlier commitments, increasing the likelihood of more signings in December than in February, further de-emphasizing the traditional National Signing Day.

Amid all those changes, though, recruits are still allowed only five official visits and only one to each school. Of course, a recruit can make multiple unofficial visits, paying for those out of his and his family’s own pocket, but Notre Dame can pay for only one. As much as getting a recruit on campus earlier in the process should bode well for any program, it becomes a double-edged sword: Is it better to get a player on campus early and make that impression before other schools have the opportunity, or is it better to showcase a primetime game against a rival?

Irish recruiting coordinator Brian Polian suggested allowing two official visits per school, although remaining at only five total, on National Signing Day.

“Why not let a young man make two official visits to one institution? Because if somebody says to us, from far distance, I want to come make a visit to your place in the spring, well, ideally you want them to see a game atmosphere, as well,” Polian said. “There’s nothing like Notre Dame Stadium and this campus on a game weekend.

“Now we’re going to have to get into some strategic decisions about when do we want young men to take visits.”

Perhaps in time the NCAA will consider that adjustment, but it will not be for the cycle of 2019.

While when a player visits may impact the recruitment, Polian does not much care about when they commit, as long as they do. Notre Dame signed five prospects on National Signing Day who had not previously committed publicly, making it appear to be a strong finish to the class. Then again, the Irish also signed 21 players in the early signing period and received a 22nd commitment less than a week afterward.

“If you’ve got a really good class and they’ve been committed for a while, who cares when they said yes?” Polian said. “It’s as though the answers that you get at the end dictate your class.”
